Hazardous Waste Warning

Wastes in this section are dangerous to you and the environment. Handle them carefully and dispose of them properly.



Legally, households may not transport more than 15 gallons of wet or 125 pounds of dry hazardous materials. Read about the regulation.

What are Hazardous Wastes?

Hazardous Wastes are materials that are either flammable, corrosive, highly reactive or poisonous. As such, they should not be put in the trash. Many chemicals used around the home, in our cars, and in manufacturing are hazardous. Expand the list below for specific examples and links to more information.

Who can use Collection Centers and Events?

Hazardous Waste events and facilities are designed for residents and small businesses. Businesses should review our Businesses with Hazardous Waste page for more details.

Each event and facility is different, so please review the information carefully. Contact the event or facility operator if you have questions.

Do not bring explosives, biohazards, radioactive materials, needles, or controlled substances to Hazardous Waste collection sites or events unless specified.

How should I transport my material?

Please make sure that all of your waste is securely contained in your vehicle. Each container should have a properly fitting lid and must be no larger than 5 gallons. Also, it's best to double-contain your material in cardboard boxes or plastic bins.

Each collection center has its own acceptance limits, so please call ahead to see how much waste you can transport at one time.
